Impossible de démarrage windows 10, “démarragerec /corrigerdémarrage” gives “accéder refusé”

My “always on” home desktop today appeared to be totally unresponsive. It was clear that I had only one choice to power reset it. At first it seemed that it booted into my login screen, but again my I did power reset by mistake. From this point on I wasn’t able to boot. It shows *“inaccessible boot device”* blue screen.

Recovery or restore doesn’t work. From cmd prompt Je vois my C:\ drive and all files seem to be ok, entire `chkdsk` shows that everything is ok with the drive.

`bootrec /FixMbr` works, however `bootrec /fixboot` gives me *“access is denied.”*

`bootrec /scanos` and `bootrec /rebuildbcd` both show *“Total identified windows installations: 0”*

J'ai essayé de run it all from the UEFI partition by enabling it from `diskpart` but I still get *“access denied”* for `fixboot`, no matter what J'ai essayé. There is one suggestion for the *“access denied”* error: to format the UEFI partition and then manually create `EFI\Microsoft\Boot\` in there and retry `bootrec /fixboot` but I find it outlandish to even consider it.

Des suggestions? What could be wrong?

J'ai exécuté into the same issue, the suggestion from Darko_65 in [Microsoft Answers forum](https://answers.microsoft.com/en-us/windows/forum/windows_10-performance/windows-10-cant-boot/5b675a98-ac85-46f1-894a-9a8ac016caec) is what a fonctionné pour moi:

"`bootrec`" command sometimes has problems finding proper boot device
and windows installation to fix.

Use "`bcdboot`" command to fix boot (bcdboot requires that partitions
are specified explicitly!)

`bcdboot C:\windows /s S:`

specifies C: as Windows partition, S: as system partition.

Use "`diskpart`" or "`mountvol`" commands to map system partition.
